Surface-Induced Recrystallization of Amorphous Calcium Carbonates to Oriented Calcite Crystals

  • T. Yong-Jin Han (a1) and Joanna Aizenberg (a1)

Abstract

Enigmatic functions of amorphous calcium carbonates (ACC) are explored by inducing the formation and the stabilization of spherulitic ACC particles on self-assembled monolayers (SAM) of hydroxy-terminated alkanethiols on Au surface. We demonstrate that the stabilized ACC particles can be induced to crystallize on command to form oriented calcite crystals by introducing a nucleating surface by a means of a secondary SAM surface with carboxylate functionality.
